WATERFORD — A man who killed himself during a standoff with Waterford police has been identified by friends as a former Marine who suffered from post-traumatic stress disorder.

Friends of 31-year-old Justin Eldridge told The Day of New London that he also suffered a traumatic brain injury during a deployment in Afghanistan.

Police found Eldridge dead in his home at about 1 a.m. Tuesday, about four hours after the standoff began. Authorities say his four children also were in the home, but were unharmed and didn't see the shooting.

The medical examiner ruled Eldridge shot himself in the head. Police are still investigating his death.

Eldridge's wife spoke of his struggles with PTSD and the traumatic brain injury earlier this year while promoting a fundraiser for the Wounded Warrior Project.
